Search for a tool or task, check its pricing, and open its official website. Freemium means a free plan with paid upgrades.

Free self-hosted UI · model costs
Chat with AI models in your own browser-based workspace.
Use the self-hosted UI with its required branding under the current license. There is no included paid-model allowance: cloud APIs, servers and storage can cost extra. Removing branding or qualifying enterprise uses may require a separate license; do not assume the current release is unrestricted BSD.

Free desktop app · separate cloud plans
Ask AI questions about your documents and files.
The local desktop app and self-hosted software have a free MIT-licensed option. Cloud hosting and selected external model APIs can charge separately. Local model use still requires your device resources; free software does not include every model provider.

Free Sandbox · paid cloud plans
Build AI chatbots and automated workflows.
Cloud Sandbox is free with limited credits and storage. The provider lists Professional at USD 590/workspace/year and Team at USD 1,590/workspace/year on annual billing, before applicable taxes. Community self-hosting uses your infrastructure; model API keys and paid features can add costs.

Free Community · paid hosting/features
Connect apps and automate repeated tasks.
Self-hosted Community runs indefinitely without a paid license key. Registered Community also remains free. Business/Enterprise features and n8n Cloud are paid; your server, third-party services and model APIs can add costs. Its source-available license is not a general permission to sell a competing service.
